Cam Phaser/ Engine Failure Poll

[NORCAL SS]

Do you have documentation that you can share, specific to vehicles built after April 8, 2019, having revised phasers and new PCM calibration? And what exactly was calibrated in the PCM? I really hope this to be accurate, considering I have May 2019 build date!

If this is correct, and the cam phaser issue has been resolved for the vehicles built after April 8, 2019, is Ford installing the phasers with the updated design (part #) AND reflashing the PCM for vehicles coming in with phaser issues? It appears that some have had the phasers replaced twice, and continue to have problems.

If PCM calibration is truly part of the root cause, I wonder if the new factory calibration carries over to those with aftermarket tunes? It appears this would be a good way for Ford to easily deny cam phaser warranty claims for anyone with an aftermarket tune.

Not sure of this info. Folks getting fixed since that date are still reporting failures.

its looks like that tsb was for 17 and 18 f150s ,the April date was referring to the navigator .

I found this thread in googling the very loud, very rapid ticking noise that I noticed my raptor making today. 300 miles on the odometer, with a sticker build date of 06-06-2019. Do I need to start worrying now and head to a dealer? It seems to disappear after the truck has warmed up and been driven for a few minutes.

Does the phaiser have any influence on the performance

This is what bad phasers sounds like and it is only when you start it up and more pronounced if it is a cold start:

Yes, if you consider stretched chain, out of time, broken internals performance.

I haven't received a recall notification, nor do I have any signs of rattling/noises, I dont need to change the phasers then ?

Nope. There is an SSM for people that have the cold start rattle, and a TSB is forthcoming. Curious what date range it identifies. Hopefully at that point, they have revised parts to fix.
